A proposal that diamonds may also form in Jupiter and Saturn, where the concentration of carbon is far lower, was considered unlikely because the diamonds would quickly dissolve. [16] Experiments looking for conversion of methane to diamonds found weak signals and did not reach the temperatures and pressures expected in Uranus and Neptune.
Neptune, like Uranus, is an ice giant, a subclass of giant planet, because they are smaller and have higher concentrations of volatiles than Jupiter and Saturn. [73] In the search for exoplanets , Neptune has been used as a metonym : discovered bodies of similar mass are often referred to as "Neptunes", [ 74 ] just as scientists refer to ...
Scientists have finally discovered how sheets of diamond rain form on the ice giants, Neptune and Uranus. The answer could explain why Neptune’s core is hot.
The researchers used plastic to recreate precipitation believed to form deep inside ice giant planets Uranus and Neptune. Diamonds rain from the sky on billions of planets, new research shows Skip ...
Jupiter's troposphere contains a complicated cloud structure. [20] The upper clouds, located in the pressure range 0.6–0.9 bar, are made of ammonia ice. [21] Below these ammonia ice clouds, denser clouds made of ammonium hydrosulfide ((NH 4)SH) or ammonium sulfide ((NH 4) 2 S, between 1–2 bar) and water (3–7 bar) are thought to exist.
In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true.
In both the ancient Greek and Roman civilizations, Jupiter was named after the chief god of the divine pantheon: Zeus to the Greeks and Jupiter to the Romans. [19] The International Astronomical Union formally adopted the name Jupiter for the planet in 1976 and has since named its newly discovered satellites for the god's lovers, favourites, and descendants.

It is designed to return data in situ on Jupiter's auroral region and magnetospheric plasmas, by observing electrons and ions in this region. [2] It is primarily focused on Jupiter, but it was turned on in January 2016 while still en route to study inter-planetary space (when it was still several million miles from Jupiter at that time).
